Nakanishi Motor Spindle Straight Code Type (7806) BMS-4040 1 unit

Catalog number: BMS-4040 Features: ●The E4000 series is the strongest spindle in the φ40mm class, achieving a maximum output of 1200W and a maximum torque of 100cN・m. ●High-precision machining is possible with spindle runout accuracy of within 1μm, and tool life is extended. ●Ceramic bearings are used, which are approximately twice as durable as steel bearings. ●A brushless motor is used, eliminating the need to replace carbon brushes and preventing carbon brush dust from entering the bearings, extending tool life. ●The overall spindle length has been shortened, making it easy to install on space-saving small NC lathes and dedicated machines.
